ir_overview vs cloudtop

[elympos]

Hello, I am a new user of satpy and it is an amazing tool!!

Can I please have any info why "cloudtop" and "ir_overview" products of MSG have the same depiction?
Where can I see the MSG channels used in each composite.

Thank you for your time!

Hi @elympos , welcome!

"cloudtop" and "ir_overview" are two variation of the same composite. They differ (slightly) in how the colours are "stretched".

You can have a look at how the composites are done here: https://github.com/pytroll/satpy/blob/main/satpy/etc/composites/visir.yaml and here: https://github.com/pytroll/satpy/blob/main/satpy/etc/composites/seviri.yaml
and how the composites are post processed here: https://github.com/pytroll/satpy/blob/main/satpy/etc/enhancements/generic.yaml and here: https://github.com/pytroll/satpy/blob/main/satpy/etc/enhancements/seviri.yaml
